ABSTRACT

Now for detection ill with high hazard
of development of menacing life of arrhythmias are used different ECG methods: a ECG of high-resolution (ECG HR), variability of cardiac rhythm, Holter's monitoring. The speaker of indexes of datas of methods is well enough investigated in acute, subacute and remote phases of a myocardial infarction.
Are to a lesser degree investigated ECG markers of sudden cardiac death (SCD)
at an ischemia of a myocardium. In this connection will convert on itself attention datas on a possibility of usage of an estimation of modifications of duration and amplitude QRS of a complex at an ischemia of a myocardium (stress-test, acute coronary set of symptoms (AÑS), chronic ischemic illness of heart) on datas a ECG HR and variability of a cardiac rhythm [10]. In accessible to us to the literature we have not met enough complete datas on the speaker amplitude both time responses of a complex QRS and indexes ÂÑÐ for ill ACS.
By the purpose of the present research was the study of indexes a ECG ÂÐ and ÂÑÐ for ill ACS for an estimation of electrical stability of a myocardium and gravity
of current of disease.
